Joe, your pH needs to be above 6.2 to 6.5 in promix/soil amended with peat moss to absorb calcium effectively. the spike in temp most likely caused the issue. probably have a buildup of excess potassium also. A flush will take better part of a week to show improvement. you can also foliar spray with a Fulvic Acid mix will show improvements in a couple of days. Get yourself a Silicon Root Beneficial's for heat and stress prevention / protection.
